Unable To Control Anger And Crying, Extremely Emotional. How To Overcome This?

Question: m 25 yrs old and i cant control my anger and crying...small things can trigger my anger and i feel like breaking stuff or hitting people and when i cant do that i end up crying..its effecting my relationship..would should i do control my anger?

i have always been a bit short tempered as far as i remember..but off late iam most of the time angry or irritated for small or no reason. Its hard for me to let go...sometimes it takes me weeks to forget things and calm myself down. Unless i truly lash my anger out or cry for hours i cant calm myself. And i usually get angry with my close ones like my family and boyfriend and friends and i dont usually care what others think or say about me unless its extreme.

i dont think i have any unresolved life situations... I am self employed..though there are small things that i want to do like painting, travelling and designing jewellery or keep a dog. My parents are supportive in whatever i do. They love me and are very calm and understanding during my episodes of anger. My parents had a troubled relationship for a while but all is well between them. They are happy together. My father had a drinking problem earlier but now he is an occasional drinker.

I dont smoke at all but i drink rarely and responsibly while im with friends

iam i sort of loner. i dont like to talk much. Iam a bit reserved though i have many friends and i stay in touch with them and they dont see me as short tempered or reserved..to them iam a bit extrovert person. When iam with friends i enjoy their company. I dont like people to know about what iam doing in my life or what Iam feeling. I try not to expect much from others and i dont like when others expect from me.

I worry a lot about loosing my freedom after i get married. Thinking about giving up my freedom and my life style makes me really irritated and angry. When I talk about this with my boyfriend i usually loose control over my emotions and we end up fighting. I Have a reputation of being rude and angry all the time. After fighting i feel guilty about loosing my temper.

my marriage has not been fixed yet but when my parents or people talk about it i get irritated thinking about the change.

i did not react in front of my parents..my father doesn't know that i know about this disturbed period..my mother disclosed it to me i just listened to her and did not react much. i talked about this with my boyfriend and after a few days i was fine with it.

my boyfriend doesn't drink and doesn't have any kind of relationship with any other girl.
We are opposite in nature. He is calm and serious in nature. He used to handle my anger calmly and patiently but now we fight more often as if he is running out of patience. We have been together for 3 years.

I have one younger sister.
